I went for the Sabol system. I have 2 Platoon-sized carry cases and just a whole lot of foam. I choose what I need to bring (for CTA I can get 2 fleets in one case) and load up.

Most ships fit in the 1.5" foam, some like the larger Brakiri ships need the 2" or 2.5". Although, I'm using that magnetic adapter system so none of my ships have the bases attached to them (which makes them smaller).
